Troubleshooting
Fix the most common instaSpace-for-Word issues — installation, sign-in and loading.
Most issues with the Word add-in fall into a few buckets. Work through these before reaching out.
The add-in doesn't appear on the ribbon
Confirm your Microsoft plan supports add-ins and that an admin hasn't restricted them. If it was deployed centrally, give it time to propagate, then restart Word.
Sign-in fails or loops
Make sure you're using the same account as on the web. Sign out and back in, and check that pop-ups or the embedded browser aren't being blocked by a policy.
The panel is blank or won't load
Close and reopen the panel, then restart Word. A stale cache is the usual culprit, and a restart clears it.
It can't read the document
Make sure the document is fully open (not in protected view) and saved, then reopen the panel.
Still stuck? Note your Word version and whether the add-in was installed individually or by an admin, and reach out to support.
